TM Heating & Cooling | Certified HVAC Services in De Motte, IN

Often, a furnace ignition failure is a repairable issue, such as a faulty igniter, flame sensor, or gas valve—common problems we see in De Motte. Our technicians will diagnose the root cause and provide a transparent repair estimate. We only recommend a full system replacement if the repair is not cost-effective or if your furnace is very old and inefficient. Our goal is to restore your heat reliably and affordably.

For most homes in our area, we recommend checking your air filter every month and replacing it at least every 90 days. If you have pets, allergies, or a lot of local dust, you may need to change it every 30-60 days. A clogged filter is a leading cause of poor airflow, system strain, and even breakdowns. Regular filter changes are the simplest way to improve efficiency, air quality, and prevent costly repairs.

Our comprehensive maintenance service is designed to catch small problems—like those that cause ignition failure—before they become big ones. We perform a full system check, including cleaning critical components, inspecting the ignition system and heat exchanger for safety, checking refrigerant levels, cleaning coils, and ensuring all electrical connections are secure. This proactive care improves efficiency, extends your system's life, and keeps your De Motte home comfortable all year.
